Preparing old laptops for autoreinstallation

From OLPC

If you have older (A,B1,B2,B3) laptop hardware, and don't know whether it is running a firmware version older than Q2C11 (2007-05-06), you need to check. If you do have the older firmware, then just press the power button; you do not have to hold the X game key and press the power button as instructed below. (B4, C, and M laptops have firmware more recent that Q2C11.)
